lThis invention has reference to an iarticle 'of manufacture whichAcomprises a fabric, "preferably made of wire and Awhich iis adapted foruse as :a

reinforcing material for concrete and other types 5 of construction inmonolithic form. Y

The invention Y'has for its principal -bject "to provide :in such a`fabric means of -a pre-'determined length forproperlyspacing the kbody"wires, constituting the fabric, from the surface 'of the material .cast'and if employed in 'construction work in connection withthe 'Walls`anc'l-ceilings-of buildings, such spacing means will propelylspace thefabric from the studding or other support, so that when plaster isapplied it will get behind the fabric so that when the wall is com;pleted the fabric will be embedded or completely surrounded by theplaster, thereby giving a stronger and more durable wall construction.

The invention has for a further object to combine the spacing means inwell known types of Wire fabrics, as for example, those types made up ofline wires or longitudinal strands and stays or pickets or cross-wiresand where the connections at the intersections of such wires comprise awrap or staple connection. An end or ends of the wraps or an end or endsof the staple ties being extended laterally or at right angles to thebody of the fabric and of such pre-determined length to properly spacethe body of the fabric from the surface of the material reinforced. Incarrying out the invention the projecting portions or extensions of theWraps may be extended laterally from only one side of the fabric or fromboth sides, as occasion or working conditions I` may require. Also, suchextensions or projections may be provided at the connection between thestays or pickets or cross-wires with the marginal or selvage wires, thesame as at the intersections of such cross-wires with the intermediateline wires.

Fig. 1 is a face view, broken away, of a wire fabric composed of lineand cross-wires, the latter comprising sections which unite at the linewires v and twisted or coiled together thereabout, an end of one of thesections of each cross-wire projecting or extending laterally from thefabric, on one side, for a predetermined distance;

Fig. 2 is an edge view, broken away, of the fabric shown in Fig. 1;

Fig. 3 is a view similar to Fig. 2 and of a like fabric as shown in Fig.l, except that the top and bottom sections of the cross-wire which arecoiled about the selvage or marginal wires have lateral terminalprojecting ends, as do certain of the intermediate sections;

Fig. 4 is a view similar to Fig. `3 except that A'the rends Aof ethe`respective Vsections vrof the Jcross- -wire Which tconnect with theintermediate line Wires *project laterally 'ffrom Aand on-opposite sidesvof the fabric, `at points `Aof intersection with said U0Ainterrnec'liate Iline Wires;

Fig. 5 xisa -view similar "to Fig. 4 except that the 'topand bottomsections ofthe -cross lwire which are coiled about the selvage ormarginal wires are"loopedback -on themselves in opposite directions toprovide lateral Aextensions lor vkprojections fon opposite -sides of`the fabric;

Fig. 6 is a fface view, -somewhat Asimilar to Fig. "1 Vexcept that thestay or cross-wire fis ya straight -or stiff 4single AWire `ltheopposite `ends 'of 7.0 which are coiled or Wrapped about the selvage ormarginal wires and with their ends projecting or extending laterallyfrom the body of the fabric, the body of the cross-wire being connectedat its intersection with the line wires by staples, an end of whichprojects or extends laterally from the body of the fabric; and

Fig. 7 is an edge View of Fig. 6.

In each of the figures the line or longitudinal wires are designated 1with the outside wires referred to as selvage or marginal wires andthose between as the intermediate wires. These wires may be spacedequidistantly from each other or in any spaced relation or arrangementas desired or working conditions require.

The stays or pickets or cross-wires are designated 2. In all the gures,except Figs. 6 and 7, these cross-wires comprise sections extending frommarginal wire to marginal wire, the meeting ends of adjacent sections atthe intermediate line wires being preferably intercoiled about suchwires, as at 3, while the outer ends of the top and bottom sections ofthe cross-wires are coiled about the marginal or selvage wires, as at 4.To provide the spacing members for the fabric, an end of certain of thesections of the cross-wire are extended or projected laterally for apredetermined distance from one side of the fabric, as at 5, at eachintermediate line wire, see Figs. 1, 2 and 3; or an end of eachalternate section of a cross-Wire may be extended or projected laterallyfor a predetermined distance from opposite sides of the fabric, as at 6and 7, at each intermediate line wire, see Figs. 4 and 5. In Figs. 1 and2 there are no projections from the terminals of the coils 4 around themarginal Wires. In Figs. 3 and 4 the terminal ends of these coils 4project laterally from the body of the fabric, for a predetermineddistance, as at 8. In Fig. 5 the terminals of the coils 4 are loopedback on themselves, as at 9, to provide eX- tensions projectinglaterally from opposite sides of the fabric. It is obvious from theforegoing description that, employing a fabric, the crosswires of whichare made of a series :of sections that the spacing members whichare'located at the intersections of the cross-Wires with the line orlongitudinal Wires may extend laterally from only one side of the fabricor from both sides as occasion or Working conditions may require;

In Figs. 6 and 7 the cross-wires, as pointed out, are uncut straightsingle Wires having their terminal ends coiled about the marginal orselvage Wires, as at 10, with the terminal ends projecting laterallyfrom the fabric, as at 11, to provide the spacing elements. Where thecross-wires 2 intersect the intermediate line Wires they are connectedby staples 12 with an end of the staples projecting laterally from thefabric, as at 13, to provide the spacing elements.

What We claim is:-

1. An article of manufacture comprising a wire fabric including line andcross-Wires connected at their intersections, certain of saidconnections provided with lateral extensions projecting from one side ofthe fabric, While certain other of said connections are provided withlateral extensions which project fromv opposite sides of the fabric.

2. A Wire fabric for reinforcing materials comprising a plurality ofspaced parallel line Wires and a plurality of spaced transverselydisposed cross-wires, and means for spacing the bodyof the fabric fromthe surface of the material Which comprises members of predeterminedlength projecting at right angles from the plane of the body of thefabric and which also constitute connecting means for the line andcross-wires Where they intersect.

3. A Wire fabric for reinforcing materials comprising a plurality ofspaced line Wires and a plurality of spaced cross-Wires, and means forspacing the body of the fabric from the surface of the material whichcomprises members of predetermined length projecting laterally fromopposite sides of the body of the fabric and which also constituteconnecting means for the line and cross-Wires where they intersect.

4. An article of manufacture comprising a wire fabricmade up of parallelspaced line Wires and transversely spaced cross wires whereby tocharacterize a square mesh fabric presenting a substantially at mat,1and means connecting said Wires Where they intersect, certain of whichsaid means having a portion With a free terminal projecting at rightangles from the plane of the body of the fabric for a predetermineddistance for seating against a supporting surface to space the fabricfrom the latter.

5. An article of manufacture comprising a Wire mesh fabric formed ofintersecting wires connectediat their intersections, certain of theconnections having extensions projecting laterally from a side face ofthe fabric, the terminals of which extensions are free for seatingagainst a supporting surface thereby to hold the fabric spaced fromysuch surface.
